You can set the page title dynamically with a macro to insert the desired name. That would prevent all pages from carrying the same title.
Go to Settings-->Content-->Metadata
Then under Page title format you can set your macro. For instance, {%prefix%} - {%pagetitle_orelse_name%}
The prefix would be what's set right below in the Page title prefix which could be the company name or something.
For documents, you can do something similar. Go to the parent folder or document, say, Articles and select Metadata from under the General tab. Uncheck Page title - Inherit, and add a macro like {%Headline%}
. You can do the same for description with a macro like {%Summary%} or some other appropriate field from your page type.
Hope that helps!
